Electrical wire

Electrical wire has been used in a wide variety of applications. Electricity is preferably transferred at a high voltage which lessens the amount of current needed for movement and lessens the associated current loss. In an electric wire used for power transmission and distribution, etc., an electric wire body is usually covered with a cover consisting of an electrically insulation material such as rubber, resin or the like in order to keep electrical insulation from articles contacting with the electric wire. High voltage transmission wires are typically constructed from aluminum, aluminum clad steel, copper, or a copper clad material and suspended from tall structures by use of porcelain or the like, non-conductive insulators. Overhead electric wires are usually carried by porcelain insulators which are maintained upright by an upstanding pin engaging an axial blind bore of the insulator body, the pin fixed to the cross-arm of a pole or tower. An electric wire insulated with a foamed plastic, which has a foamed fluoroplastic as an insulating layer is widely used as plenum coaxial cables or signal transmitting electric cables used in electronic equipment. Electrical connectors are typically required in order to couple together an electrical wire with another piece of electrical equipment. The other piece of electrical equipment can be another wire, metal foil, or electrical components. Electrical wire is typically sold on spools or in containers containing a total amount of wire length determined in part by the cross-sectional area of the conductor.
